Ah, one big preload is smart.
I like where you've taken the typing game idea though. The counter curses being opposites of "negative" words works so well - its basically training the players to think positively when they see negative words. It would be interesting to see if you could remove the UI for the positive words at a certain point and still have the player type them. I didn't get up into the high levels so apologies if it already does something like this.
